To all whom it may concern:

Be it known that.

For securing the sash in position I provide anchors engageable with the side bars of the sash and having a portion which may be embedded in the masonry. These anchors are preferably fin-med of angle bars D, one flange E of which projects outward While the flange F is adapted to tit within the channel of the bars A. There is also preferably formed a groove or rabbet G which receives one flange of the channel bar and Forms a llush joint with the outer face thereof. During the construction. of the masonry bars 1) are set with the flange E projecting into a recess and suitably secured as by embedding in cemel'lt. The bars D upon opposite sides of the window are properly lined up and are spaced to receive the sash frame. The sash may then at any time he engaged with the anchors 1) being positioned by the engagement of the llange I with the channel of the bar and being sccurcd by screws such as H.
